A reactive dog is one who responds to specific triggers — other dogs, strangers, cyclists, skateboards — with explosive behavior: lunging, barking, spinning at the end of the leash. It’s exhausting, embarrassing, and stressful for both dog and owner. But reactivity is very manageable with the right approach.
Reactivity vs. Aggression
Most reactive dogs are not aggressive — they’re anxious. The explosive behavior is a stress response, often rooted in fear (“get away from that thing before it hurts me”) rather than genuine offensive intent. This distinction matters enormously for treatment approach.
The Foundation: Threshold Management
Every reactive dog has a “threshold” — the distance at which they can perceive a trigger without exploding. Work consistently below this threshold. If your dog reacts, you’re too close. Increase distance until you find where they can see the trigger and remain (just barely) calm.
Look at That (LAT) Game
When your dog looks at a trigger below threshold, say “Yes!” and reward. You’re teaching: trigger = look at me = reward. Over hundreds of repetitions, the emotional response to the trigger begins to shift from anxiety to anticipation of good things.
Building the Foundation Through Brain Training
Reactive dogs benefit enormously from building a strong reward history with their owner — which is exactly what creates. Dogs who find working with their owner deeply rewarding are more responsive during reactive moments and recover faster. Also see our anxiety guide — reactivity and anxiety are closely linked.
